Etsy user greyskieseternal has found a clever way for teachers to let their students know that they’re failing with this Lord Of The Rings-inspired self-inking stamp that reads “You Shall Not Pass.”

The stamper prints out the words in red and even has a tiny Gandalf on the left with sword and staff in hands acting out how you shall not pass, as if your horrible test scores were the Balrog itself.

The stamper is available for pre-order right now through greyskieseternal’s Etsy shop and costs $10 plus shipping when you pre-order. New orders will be shipped on March 10.

Even though I’m not a teacher and would basically have zero use for this stamper, I feel that it’s just too awesome not to get, so I’m thinking I’m going to have to order one for myself. Check out the image below of how it looks stamped out and tell me you don’t want one of these for yourself!
